摘要：

In this study, new backward and forward bent wings with bend angles of 10 degrees and 20 degrees were developed and attached to the subsoiler foot. Effects of new wings on the subsoiler performance were compared with subsoilers with conventional wings and non-wings. Rake angle of all wings was 15 degrees. The effects of new wings on the imposed horizontal and vertical forces, soil loosening and upheaving area, specific draft, bulk density and after-till penetration resistance were investigated using randomized complete block design. The subsoilers were operated at a depth of 40 cm in a clay loam soil. Results showed that the effect of wings on all parameters was significant (p<0.01). By adding wings to the subsoiler foot, horizontal and vertical forces, soil loosened and upheaved area increased but specific draft, soil bulk density, and penetration resistance decreased. Among all wings, 10 degrees forward bent wing showed the best performance and is suggested as a suitable attachment for deep soil loosening.
